For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

Coconut oil coffee, which is popular in Japan's weight-loss circle, has become a weight-loss sacred product after a big meal at the end of the year, promoted by bloggers and artists.

Japanese girls invented this trick by adding a spoonful of coconut oil to the coffee and beating it in the blender for 20 seconds. The medium-chain fatty acids in it are said to resist blood sugar and help lose weight. Others add all kinds of hot drinks to coconut oil, or recommend drinking a spoonful of coconut oil before meals to suppress appetite and achieve weight loss.

However, dietitians warn that if you want to lose weight with coconut oil, you should pay attention to reducing your total oil intake instead of eating more. Coconut oil can be used to replace the current cooking oil, but not to add extra coconut oil to drinks and meals.

1. Does coconut oil really help you lose weight?

Not necessarily. Indeed, some studies have pointed out that changing daily edible oil to medium-chain fat for 3 to 16 weeks can reduce body weight by 0.5 to 0.7 kilograms and body fat by 0.4 percent, but the problem of regaining weight after short-term weight loss has not been further explained.

The fatty acids in coconut oil are mainly medium-chain fats. In an article discussing coconut oil in the Science and Technology Grand View Park, Xiao Ningxin explained, "(medium chain) is smaller and dissolves faster than long-chain molecules, and the fatty acids produced by digestion can be quickly absorbed by the small intestine and transported to the liver through the hepatic portal vein for oxidation and metabolism." it is a kind of quick-acting energy, but it can also increase the effect of heat production and may control body weight. "

On the other hand, coconut oil has the highest percentage of saturated fatty acids among all kinds of edible oils. without excessive intake, coconut oil is used to replace other oils. although the total calories remain the same, saturated fat increases.

two。 Does coconut oil increase good cholesterol?

A large-scale study jointly conducted by the United States and the Philippines has found that the more coconut oil is consumed, the higher the concentration of total cholesterol and triglyceride in addition to the increase in good cholesterol. And in fact, the ratio of total cholesterol to good cholesterol has not changed.

3. Does coconut oil affect cardiovascular health?

Saturated fat in coconut oil may still have cardiovascular effects.

So far, dietary guidelines issued by governments around the world have recommended limiting the intake of saturated fat. The American Heart Association still recommends that the daily intake of saturated fat should not exceed 13 grams.

4. Coconut oil contains substances that boost immunity?

The efficacy of coconut oil mainly follows the vein of medium-chain fatty acids, especially lauric acid; the saturated fatty acids of coconut oil are as high as 92%, of which lauric acid is the largest, accounting for 47.5% of all saturated fatty acids. In addition to the different metabolic pathways of medium-chain fatty acids and long-chain fatty acids, medium-chain fatty acids may help control weight, but also have some additional benefits.

The International Office of the Council of Agriculture of the Executive Yuan points out in an article that the medium-chain fatty acid lauric acid, which is rich in coconut oil, is converted into Monolaurin in the human body, "which can destroy the fat membranes of many viruses and bacteria, making it inactive. "therefore, coconut oil also contains substances that increase the body's immunity.

However, Cheng Hsin-hsien, an honorary professor in the Department of Health and Nutrition at Taipei Medical University, points out that although coconut oil has medium-chain fatty acids, when we use coconut oil, "it is impossible to eat only lauric acid. Other things (such as long-and short-chain saturated fats) will also be eaten. "

Dietitians suggest that oil is the healthiest way to use it.

● daily oil intake standard is 3: 6 teaspoons, too much is not good, meet the daily recommended oil intake, in order to promote balanced absorption of nutrients.

It is best to choose small bottles of ● oil to ensure that it is fresh and should be replaced. Do not use a certain oil every day because of its health and nutrition.
